4.2 Electrical connection
DANGER
Voltage on the device
Electric shock
→ Always connect a protective earth first.
→ Check the protective earth.
DANGER
Faulty insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
regulations for voltage, current, insulation material, capacity,
etc.
→ Route cables so that they cannot be touched by any
rotating parts.
DANGER
Electrical charge (>50 µC) between phase conductor and
protective earth connection after switching off supply
with multiple devices connected in parallel.
Electric shock, risk of injury
→ Ensure sufficient protection against accidental contact.
Before working on the electrical hookup, short the supply
and PE connections.
CAUTION
Voltage
The fan is a built-in component and has no disconnecting switch.
→ Only connect the fan to circuits that can be switched off with
an all-pole disconnection switch.
→ When working on the fan, secure the system/machine in
which the fan is installed so as to prevent it from being
switched back on.
NOTE
Device malfunctions possible
Route the device's control lines separately from the supply line.
→ Maintain the greatest possible clearance.
Recommendation: clearance > 10 cm (separate cable
routing)
NOTE
Water ingress into wires or cables
Water ingress at the customer end of the cable can damage the
device.
→ Make sure the end of the cable is connected in a dry
environment.
Only connect the device to circuits that can be switched off with
an all-pole disconnection switch.
4.2.1 Requirements
; Check whether the information on the nameplate matches the
connection data.
; Before connecting the device, make sure the power supply matches
the device voltage.
; Only use cables designed for the current level indicated on the
nameplate.
For determining the cross-section, note the sizing criteria according
to EN 61800-5-1. The protective earth must have a cross-section
equal to or greater than that of the phase conductor.
We recommend the use of 105 °C cables. Ensure that the minimum
cable cross-section is at least
AWG 26 / 0.13 mm².
Protective earth contact resistance according to EN 61800-5-1
Compliance with the resistance specifications according to EN 61800-5-
1 for the protective earth connection circuit must be verified in the end
application. Depending on the installation situation, it may be necessary
to connect an additional protective earth conductor by way of the extra
protective earth terminal provided on the device. The protective earth
terminal is located on the housing and provided with a protective earth
symbol and a hole.

4.2.3 Reactive currents
Because of the EMC filter integrated for compliance with EMC
limits (interference emission and immunity to interference),
reactive currents can be measured in the supply line even
when the motor is at a standstill and the line voltage is switched
on.
● The values are typically in the range < 500 mA.
● At the same time, the effective power in this operating state
(operational readiness) is typically < 6 W.
4.2.4 Residual current circuit breaker (RCCB)
If the use of a residual current device (RCD) is required in your
installation, only AC/DC-sensitive residual current devices
(type B or B+) are permissible. As with variable frequency
drives, residual current devices cannot provide personal safety
while operating the device. When the device power supply is
switched on, pulsed charging currents from the capacitors in the
integrated EMC filter can lead to the instant tripping of residual
current devices. We recommend the use of residual current
circuit breakers (RCCB) with a trip threshold of 300 mA and
delayed tripping (super-resistant, characteristic K).
4.2.5 Leakage current
For asymmetrical power systems or if a phase fails, the
leakage current can increase to a multiple of the nominal value.

Fig. 2: Connecting wires to terminals
; Seal the terminal box.
4.3.3 Cable routing
Water must be prevented from reaching the cable gland along the cable.
NOTE
Damage caused by moisture penetration.
Moisture can penetrate into the terminal box if water is
constantly present at the cable glands.
→ To prevent the constant accumulation of water at the cable
glands, the cable should be routed in a U-shaped loop
wherever possible.
→ If this is not possible, a drip edge can be produced by
fitting a cable tie directly in front of the cable gland for example.
Fans installed lying flat

6.1 Cleaning
To ensure a long service life, check the fans regularly for proper
operation and soiling. The frequency of checking is to be adapted
accordingly depending on the degree of soiling.
DANGER
Risk of injury from rotating fan.
→ Only clean when not in motion. Do not disconnect the fan
from the power supply, just switch it off via the control input.
This will prevent start-up of the fan.
; Dirt deposits on the motor housing can cause overheating of the motor.
; Soiling of the impeller can cause vibration that will shorten the service
life of the fan.
; Severe vibration can destroy the fan.
; In such cases, switch off the fan immediately and clean it.
; The preferred method of cleaning is dry cleaning, e.g. using
compressed air.
; Do not use aggressive cleaning agents!
NOTE

; If severe corrosion is visible on load-bearing or rotating parts, switch
off the device immediately and replace it.
; Repair of load-bearing or rotating parts is not permitted!
; Operate the fan for 2 hours at maximum speed so that any water that
has ingressed can evaporate.
; If cleaning does not eliminate vibrations, the fan may need to be
rebalanced. To have it rebalanced, contact ebm-papst.
; The fan is equipped with maintenance-free ball bearings. The lifetime
lubrication of the ball bearings is designed for a service life of 40,000
